Final answer:
The correct Spanish word to complete the sentence is 'cicatriz', which means 'scar'.
Step-by-step explanation:
The Spanish word that best completes the sentence is cicatriz, which means 'scar' in English. In the given sentence, it is mentioned that someone has a scar on their leg. So, 'corte' (cut) and 'dolor' (pain) cannot be the correct answers. 'Ocicatriz' is the correct spelling. The letter 'o' in the beginning of the word is incorrect and should be removed.
